I have an RadPane and inside a RadTreeView. When I now change the width of the pane (by runtime) the width of the RadTreeView does not change. Equally when I undock the pane.
What did I have to do that the RadTreeView always has the width of the RadPane?
I have found how to do what I want.
Horizontal and vertical alignment of the TreeView is the anwer of all my problems. Don't know why I have not seen them.
